Yesterday I filled up a Sandisk 8 GB SDHC card with ROMS (about 6 GB in total). When I put the card back into the M3 Real and booted up, it was all garbled (icons missing, wrong filesizes). Chkdsk showed a lot of frayed entries.

Before that I had 3 GB of data on it and it worked flawlessly. I fear that I may have a fake (although bought at Amazon.com), because the error showed now that I went over 4 GB or the M3 real (sakura) messed it up.

I browsed through some threads and there are people using 16 GB SDHC. So where is my mistake?

Split the games up into 2 folders. NDS1 (A-M) NDS2 (N-Z). Then load your games via the FOLDER (third from the left on the main menu) symbol by selecting whatever game you want from either NDS1 or NDS2 folders. Same thing happened to me, and this fixed it. Hope this helps.

It has something to do with the M3 being able to recognize over 128 files. At least thats what I have gathered from other threads.
